What's happening to the Obama electoral coalition?

From a report at the link below:

Nearly two years ago, the political world could only marvel at the breadth of voter support for Barack Obama.

He energized a coalition -- made up of blacks, women, Latinos, young voters and large numbers of suburbanites -- that some believed would keep Democrats in power for years to come.

A scant 20 months later, the Obama coalition is frayed and frazzled.

Surprisingly, support for the president among Latinos, young people and women has dropped as much as it has among groups that were considered less likely to stick with the president, such as white males, according to an analysis by the Pew Research Center for the People & the Press.

Support among suburbanites has dropped dramatically too, surveys show, while African American voters remain Obama's most loyal constituency and his fiercest defenders.

The Pew Research Center survey experts routinely ask respondents to characterize the president in a single word.

In their most recent poll, conducted this summer, more respondents than ever answered with the word "disappointing."
